Probing beyond the Epoch of Hydrogen Reionization with 21 Centimeter Radiation [PDF]
Astrophys.J.596:1-8,2003, 2003 We use numerical simulations of hydrogen reionization by stellar sources in the context of LCDM cosmogonies to investigate the 21 (1+z) cm radio signal expected from the diffuse intergalactic medium (IGM) prior to the epoch of reionization breakthrough at redshift z_ion.

High resolution simulations of the reionization of an isolated Milky Way - M31 galaxy pair [PDF]
, 2013 We present the results of a set of numerical simulations aimed at studying reionization at galactic scale. We use a high resolution simulation of the formation of the Milky Way-M31 system to simulate the reionization of the local group.

1,1-Ethenediol: The Long Elusive Enol of Acetic Acid. [PDF]
Angew Chem Int Ed Engl, 2020 Finally made: The hitherto unreported 1,1‐ethenediol, the higher energy tautomer of acetic acid, was synthesized and spectroscopically characterized. It can be readily prepared through thermal decarboxylation of malonic acid, as has generally often been implied in the synthetically highly valuable reactions of 1,3‐dicarboxylic acids.

Simulating Reionization: Character and Observability [PDF]
AIP Conference Proceedings, 1999 In recent years there has been considerable progress in our understanding of the nature and properties of the reionization process. In particular, the numerical simulations of this epoch have made a qualitative leap forward, reaching sufficiently large ...

Cosmic Reionization On Computers: Reionization Histories of Present-day Galaxies [PDF]
The Astrophysical Journal, 2019 We examine the reionization history of present-day galaxies by explicitly tracing the building blocks of halos from the Cosmic Reionization On Computers project. We track dark matter particles that belong to $z=0$ halos to trace the neutral fractions at corresponding positions during rapid global reionization.

Cosmological reionization [PDF]
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2000 In popular cosmological scenarios, some time beyond a redshift of 10, stars within protogalaxies created the first heavy elements; these systems, together perhaps with an early population of quasars, generated the ultraviolet radiation and mechanical energy that reheated and reionized the cosmos.

The epoch of reionization [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We have modelled the process of reionization of the IGM by photoionization by galaxies, in order to predict the epoch of reionization. We use a sophisticated semi-analytic model to track the formation of galaxies. Our study represents a much more complete and physically consistent modelling of reionization than has been conducted in the past ...
